  13.    * Portable Interceptors Current (also known as <code>PICurrent</code>) 

  14.    * is merely a slot table, the slots of which are used by each service to 

  15.    * transfer their context data between their context and the request's or 

  16.    * reply's service context. Each service which wishes to use PICurrent 

  17.    * reserves a slot or slots at initialization time and uses those slots 

  18.    * during the processing of requests and replies.

  19.    * <p>

  20.    * Before an invocation is made, PICurrent is obtained via a call to 

  21.    * <code>ORB.resolve_initial_references( "PICurrent" )</code>. From within 

  22.    * the interception points, the data on PICurrent that has moved from the 

  23.    * thread scope to the request scope is available via the 

  24.    * <code>get_slot</code> operation on the <code>RequestInfo</code> object. 

  25.    * A PICurrent can still be obtained via 

  26.    * <code>resolve_initial_references</code>, but that is the Interceptor's 

  27.    * thread scope PICurrent.
